-----------------------------------
Summary: Parquet Reader exception - ArrayIndexOutOfBound should
give more information to user
Key: SPARK-26844

Point if ArrayIndexOutOfBoundsException raised on a column/field spark should
say what particular column/field it is. it helps in troubleshoot.
e.g. I get following error while reading same file using Drill reader.
org.apache.drill.common.exceptions.UserRemoteException: DATA_READ ERROR: Error
reading page data File: /.../../part-00016-00000-m-00016.parquet *Column:
GROUP_NAME* Row Group Start: 5539 Fragment 0:0
I also get more specific information in Drillbit.log
